There's so much wrong with Matthias! He's a demon, to start. But he's not to keen on revealing that to humans. He doesn't plan to reveal it to Seong, either. What's it have to do with anything anyway?

Matthias lifts his glass this time, holding it out for Seong to clink. "I'll drink to us. To you, me, and wherever we find ourselves wrapped up in each other."
